“Lindsay is dropping the Lohan and just going by Lindsay. Plus, me and [younger daughter] Ali will be officially changing our last names back to my maiden name, Sullivan.”

A family friend adds:

“So many of the greatest people in showbiz are known by just their first name. Look at Oprah and Beyonce. Now you can add Lindsay to that list. And it’s a way for them all to start over. No one in the family want anything to do with Lindsay’s father [Michael Lohan] anymore and that includes sharing a last name.”
